Genome sequence of the clover-nodulating Rhizobium leguminosarum bv. trifolii strain SRDI943

Rhizobium leguminosarum bv. trifolii SRDI943(syn. V2-2) is an aerobic, motile, Gram-negative, non-spore-forming rod. SRDI943was isolated from a nodule recovered from the roots of the annual clover Trifoliummichelianum savi cv. paradanathat had been inoculated with a soil collected from a mixed pasture in Victoria, Australia. SRDI943 has a broadhost range for nodulation within the clover genus, however N2-fixationis sub-optimal (20-54% of reference strain WSM1325) on T. subterraneum spp.Here we describe the features of R. leguminosarum bv. trifolii strain SRDI943, together with genomesequence information and annotation. The 7,412,387 bp high-quality-draft genomeis arranged into 5 scaffolds of 5 contigs, contains 7,317 protein-coding genesand 89 RNA-only encoding genes, and is one of 100 rhizobial genomes sequencedas part of the DOE Joint Genome Institute 2010 Genomic Encylopedia for Bacteriaand Archaea-Root Nodule Bacteria (GEBA-RNB) project.
